The HZZD Series is a high‑capacity, multi‑deck rotary screen cleaner designed specifically for quinoa and other small‑seeded grains. Built with a four‑group, eight‑layer configuration, it removes impurities of all sizes in one pass – from large husks and sticks to fine dust and sand – while preserving the integrity of the delicate quinoa kernel.
How It Works
The machine uses a gentle plane rotary motion, suspended by hanging rods for stable, low‑vibration operation. Material is evenly distributed across multiple screen layers via a vibrating pressure gate and multi‑channel feeder. Each layer can be fitted with different mesh sizes, enabling simultaneous separation of coarse, medium, and fine contaminants. An integrated air aspiration system extracts light impurities (chaff, dust) for superior final purity.
Why It’s Perfect for Quinoa
-
Precision screening – fine meshes handle quinoa’s small size (1.5–2.5 mm) with accuracy.
-
Multi‑stage cleaning in one pass – removes all impurity categories without re‑circulation.
-
Gentle handling – the rotary motion minimizes kernel damage, crucial for seed quality and visual appeal.
-
High throughput – capacities from 120 to 220 tons per hour, ideal for commercial processors.
-
Excellent removal rates – over 99% for light impurities and 94% for heavy impurities.
